• reduced namespace pollution
• fixed copy-past glitches and warnings

SPARQL parser

• exclude anonymous vars from select *
• preserve order of BGPs in einsum notation
• fixed #46 (parsing of * queries without variables)

Tools

• use csv-parser
• serialize statistics on nodes in IDs2Hypertrie.cpp

1.1.0-rc10

1.1.0-rc5

changes since 1.1.0-rc4

• updated version to hypertrie/0.6.0-rc9
• enabled lsb-unused
• updated dockerfile build and added CPU specific optimizations.
• use minimal version of tcmalloc
• support lld as linker
